FLUSHING APPARATUS.

Specification of Letters Patent.

Application filed July 2, 1914. Serial No. 848,562.

T all whom it may concern:

Be it known that I, HERMAN A. THOMP- SON, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Flushing Apparatus, of which the following is a specification.

This invention relates to improvements in flushing apparatus and has for its object, to provide an apparatus of this character particularly adapted for use with water-closets and the like, and one which is simple in construction, inexpensive to manufacture and compact in form. 1

Another object is to provide means in a device of this character for stopping the flow of water therethrough at any time desired without waiting for the full action of the apparatus. I attain this object by means of the improvements illustrated in the drawings accompanying this specification, in which Figure 1 is a side elevation of the complete flushing apparatus, part of it being shown in section for the purpose of better illustration. Fig. 2 is a top plan view of the device as shown in Fig. 1. Fig. 3 shows a detail bottom plan view of the valve closing disk. Fig. 1 shows a side elevation of: a modified form of valve closing disk in which the wire guides are supplanted by guide fingers integral with the disk.

Referring to the drawings, 1 designates a water supply pipe emerging from the floor, 2 and carrying a reducer, 3 which is adapted to have attached to it a vertical tube or cylinder, 4. A valve casing, 5, is threadedly attached to the upper end of the cylinder, 4, and forms a cap for it asshown, and is provided with a recess at 6 forming a water chamber opening downwardly into the cylinder, 4:. An outlet pipe, 7 is threadedly secured in the casing, 5, so as to register with the chamber, 6, and leads from said chamber to the water-closet or other device which is to be flushed with water.

It will be noted that the construction described provides a continuous water passage from the supply pipe, 1, to the outlet pipe, 7. In order to close this passage either automatically after a certain volume of water has passed through it, or by hand as described, a valve and valve closer are provided.

A cylindrical valve stem is shown at 8 upper end at-a slightdistance above the.

casing in an eye, 9. At the lower end of Patented July 13, 1915.

the valve stem a valve, 10, and a stiffening disk, 12, are attached by means of nuts, 11, f

the valve, 10, being adapted to engage the valve seat, 13, so as to close the opening of the chamber 6, by raising the valve stem within its bearing in the casing. To prevent the leakage of water through the bearing surrounding the valve stem, 8, a stufling box is provided in the casing at 14, a stuffing nut, 15, being threadedly held therein for the purpose of compressing the packing, 16, to make a water-tight joint.

The valve could be opened or closed by hand by grasping the eye, 9, of the valve stem, but it is found more desirable to attach a handle thereto for the purpose of manipulation. To attain this end, the casing 5 is provided with an upwardly and outwardly extending bracket, 17, to which a lever, 18, having a handle, 19, is pivotally attached at 20 after passing through the eye, 9, of the valve stem. As shown, the lever, 18, may be utilized to open or close the valve which after being closed will remain so, on

means other than the water pressure as the water, in this position of the valve, may pass around its edge without exerting any considerable amount of upward pressure on the valve.

An automatic closer for the valve is pro- I vided by a closing disk, 21, having anorifice,

22, through its center large enough to pass over the lower nut, 11, so that the disk may be brought into contact with thestifl'ening disk, 12, for the purpose of raising and closing the valve, as shown at 21*. The'disk, 21, is made somewhat smaller than the inside diameter of the cylinder so as to permit a small amount of water to pass it when the valve is closed and thus allowing it to drop to the bottom of the cylinder, its downward velocity being increased by the additional loss of resistance occasionedby the orifice 22.

To guide the disk in its travel through the cylinder and prevent it turning on edge, it is provided with U shaped wire guides,

23, which are rigidly attached to its under side and also form legs for the disk to hold it above the bottom of the cylinder. In Fig. at is shown a modified form of valve closing disk 21 in which the U shaped wire guides, 23, are supplanted by legs 24, formed in- .tegral with the disk.

In use, the handle, 19', is depressed to open the valve for the purpose of flushing the water-closet or other device and the valve closer, 21, being at the bottom of the cylinder as shown in Fig. 1 will then be forced to rise on account of its having a smaller water passage than the valve opening. When the closer, 21, has reached the position, 21, in contact with the stifi'ening' disk, 12, the orifice, 22,- will be entirely closed and consequently the water pressure below the closer will be sufiiciently increased to raise the valve, 10, and close it. As stated before the valve may be closed by hand if desired without waiting for the action of the automatic closer.

What is claimed is:

1. A device of the character referred to comprising a vertical water container connected at its lower end with a source of'water supply and at its upper end with an outlet therefrom, a valve in the upper end of said water container adapted to close the outlet therefrom, means for manually raising and lowering said valve into closed and open positions, a valve actuator of disk-like form in said container adapted to normally rest at the bottom thereof above the inlet thereto, said valve actuator being adapted to be raised with the infiowing water substantia'lly throughout the height of said container and to engage and close said valve in the upper end of said water container, substantially as shown and described.

2. In a device of the character described, acylindrical water container connected at its lower end with a supply pipe and at its upper end provided with a valve casing connected to an outlet pipe, a valve mounted in said water container to control the outlet ther'efroi'n a lever pivotally mounted on said valve casing and operatively connected to said valve, whereby to move the latter downwardly into open position, or to raise it to close the outlet opening from said water container, and a valve actuator of disklike form provided with a central opening and with guide members and normally rcsting in the bottom of said water container 7 above the inlet thereto, said valve actuator being adapted to be raised from the lower end of said water container to the upper end thereof by the inflowing water and to engage and positively close said valve member, substantially as described.

In testimony whereof, I affix my signature in presence of two witnesses V, E.- HoLs'roN, ALBERT J MATTOR;
